Default RE: Long time no see! Here's some spine tester results....

SA-

My readings were average deflection of each shaft as it was rotated. I noted that the max wobble within a shaft (difference from weak side to stiff side) for the Epics was over .007", and the max wobble for the ACC's was almost .005". Only a couple of shafts had noticeable wobbles to them of more than a .003-.004". Not too bad

I always cut off from both ends when assembling new arrows. Seems that you'll mostly find the runout variances on towards the factory ends.
I've measured as much as .085 variation on some dozens. I've even seen single arrows with the stiff side being .030 stiffer than the weak side.
Yup, that's why I built my tester in the first place. I don't believe too many marketing claims until I can prove it to myself! Some spine toleraces on some arrows are pretty scarey.
